Test Standard Category


Bitumen emulsion is a mixture of fine droplets of bitumen and water. The average range of bitumen mixed is from 40 to 70% on the total weight.

Based upon the time taken by the water to evaporate, bitumen emulsion is further classified into 3 types based on setting time:

  • Slow setting emulsion
  • Medium setting emulsion
  • Rapid setting emulsion

Different tests can be done to evaluate the bitumen emulsion quality, depending which parameter has to be checked. The most important are:

  • Water content
  • Setting time
  • Residue on sieving
  • Storage stability
